2 Claims. I l

The present invention relates to a metal tearing strip container or canhaving an interior collar arranged inside of the tearing strip and hasparticular reference to an improved construction of container of thistype which has a lined reclosure cover within the sealed containerhaving threaded engagement with the collar when enclosed within the can,such a cover being made eflective for hermetically reclosing the openedcontainer after removal of the tearing strip in opening the container.

An object of the present invention is the provision of an interiorcollar tearing strip can wherein a-reclosure cover has threadedengagement with the collar and within the sealed can, the opening of thecan by removal of the tearing strip releasing the reclosure cover foruse in reclosing the can.

Another object of the invention is the provision of a hermetic air tighttearing strip can having a collar hermetically secured to the body wall,the collar providing a threaded seat for a reclosure cover confinedcompletely within the can, such a cover being made effective forhermetically reclosing the opened can after the removal of the tearingstrip in opening the same.

Numerous other objectsand advantages of the invention will be apparentas it is better understood from the following description, which, takenin connection with the accompanying drawings, discloses a preferredembodiment thereof.

Referring to the drawings:

Figure 1 is a perspective view of a tearing strip container embodyingthe present invention;

Fig. 2 is an enlarged sectional view taken substantially along thesection lines 22, Fig. l, and illustrating the can parts in theirinitial condition with a reclosure cover confined within the sealed can;and

Fig. 3 is a view similar to Fig. 2 but of the opened can after thetearing strip has been removed and the initial can cover has beendiscarded, the view showing the reclosure cover in its air-tightreclosing position.

The present invention. embodies a container having a body H and endclosures l2 secured thereto in double seams l3. The usual sealing gasketor compound lining I4 is used in the seams l3 to make the same hermetic.

An interior collar l5 islocated inside of the body ll adjacent the upperend of the body, adjoining collar and body beads l6, l1 (Fig. 2)becollar and the body connection is also made as an air-tight joint andfor this purpose the body scored with a pair of parallel score lineswhich include a lower score line 2| and an upper score line 22 settingoff a tearing strip 23. At the side seam of the container, the tearingstrip terminates in a tongue 24 which provides for engagement of theusual opening key. The two s'core lines 2|, 22 preferably are cut on theinterior wall of the body in the usual manner.

The collar l5 at the lower score line 2| is formed with an inwardly andupwardly extending double rounded corner 25 which merges into a verticalwall 26 spaced inwardly from the body wall II and of a smaller diameter.At the top the interior wall 26 terminates in an inwardly extendingreclosure curl 21 which provides a smooth mouth for the openedcontainer. The body wall H above the upper score line extends into theupper double seam l3, this portion of the body wall being designated bythe numeral 3 l,

A reclosure cover 35 is contained within the can and is of suchconstruction as to be lightly carried on the interior collar- 3 when thecan is sealed initially but is made usable as a reclosure member whenthe container is openedv by removal of the tearing strip 23. This coverhas a cylindrical skirt 36 which terminates in an outwardly extendingedge curl 31 at the bottom. The diamclined conical wall 43. At theinside and at the top the conical wall 43 extends by a gentlycurvedcorner 44 into a central panel 45, Preferably the plane of the centralpanel 45 passes through the top of the arched section 38 so that thecover 35 constitutes in effect a flush cover. Cooperating threads 48, 49are formed respectively in the collar wall 26 and in the cover skirt 36.

A sealing gasket 5| is disposed in the annular groove formed on theunder side of the arched cover wall portion 38, At the time the can isready to be initially closed by seaming of the top end l2, the reclosurecover is loosely applied to onto the can and it is fully sealed (as inFig, 2)

there is no danger of the enclosed reclosure cover 35 becoming unscrewedeven 'though it is only loosely applied as the cover l2 prevents suchdisplacement.

Upon removal of the tearing strip 23, the top cover l2 together with thedetached body wall 3| may be thrown away as no longer of service. Thecan then may be fully opened by unscrewing the reclosure cover 35. Theopened container thereafter may be hermetically sealed as often asdesired merely by threadedly engaging the cover and the collar threadsand rotating the cover. By screwing down tightly, the gasket 5| iscaused to press down against the collar curl 21 so that the curl becomesembedded in the gasinvention or sacrificing all of its materialadvantages, the form hereinbefore described being merely a preferredembodiment thereof.

Iclaim:

1. In an air-tight sheet metal container ca pable of air-tightreclosure, a container bodyhav- 'ing score lines defining a removabletearing strip for opening the container, end closures for sealing theopposite ends of said body, a collar located inside of said body andhermetically secured at its inner end thereto, the upper part of saidcollar being spaced inwardly from said tearing strip, said collar havingan upper portion extending inwardly and thence upwardly to provide acylindrical wall terminating-at the top in a reclosure c'url, a separaterotatable reclosure cover seated on said collar and disposed entirelywithin said container and said top end closure, said cover having adepending cylindrical skirt and an inwardly spaced annular reclosuregasket channel, a sealing gasket in said cover channel for engagementwith said collar curl, and interengaging means on the cylindrical wallof said collar and on the cylindrical skirt of said reclosure cover fordrawing said reclosure cover into an air-tight seal with said collar byembedding said collar curl into said reclosure cover gasket, the

removal of said tearing strip to open the con-' tainer permitting thehermetic reclosing of the opened container by said reclosure cover,

2. In an air-tight sheet metal container capable of air-tight reclosure,a container body having score lines defining a removable tearing stripfor opening the container, top and bottom end closures for sealing theopposite ends of said body, a collar located inside of said bodyadjacent said tearing strip and hermetically headed at its inner endinto said body in anv air-tight seal, said collar'extending inwardly toprovide a cylindrical wall terminating in a reclosure curl spacedinwardly from the body wall, a separate rotatable reclosure cover seatedon said collar and entirely confined within the sealed container anddisposed beneath said top end closure, said cover having a verticallydisposed depending cylindrical wall fitting outside of the cylindricalwall of said collar, a sealing gasket in said reclosure cover in.vertically disposed alignment with said collar curl, and cooperatingthreads in the cylindrical walls of said collar and said reclosure coverrespectively, said threads being rendered operative by removal of saidtearingstrip and said top end closure to open the container, to form anairtight seal'between said reclosure cover and said collar by drawingthe reclosure cover gasket tightly in embedded engagament against the reclosure curl of said collar, thereby again hermetically sealing thecontainer for reclosure pur- I poses.
